Hi Andrea,
The problem appears to be that /TRENBERT/CTGAN/U/TAV/ET429707M is not in
CCM history format. Unfortunately the old no-longer-supported CCM
processor wrote several output formats in addition to writing the CCM
history format (i.e., the format produced by the CCM). Also unfortunately
some of these non-standard formats have been used in some data products
meant for general use.
Since you have access to NCAR Crays I believe that the best approach to
reading this data would be to make use of the CCM processor on paiute
(/ccm/proc/Processor). That is the only place that I know of where it
still exists. If the processor will read the data then you could write it
back out in CCM history format and then use ccm2nc. Documentation on the
processor is available at http://neit.cgd.ucar.edu/cms/processor.html.
ccm2nc is available in /fs/cgd/csm/bin/C90 for the C90 (antero) and in
/fs/cgd/csm/bin/J90 for the J90s.
Good luck,
Brian
